Mark Stull of Christoval, TX was an early “extreme” user of PerfectFlite electronics.  In 2003 Mark was developing  inexpensive, minimum diameter K powered launch vehicles to propel a radiosonde beacon to 20,000’ for atmospheric research.  He used numerous different configurations; single stage, two stage, and boosted dart.  One two-stage K to I vehicle broke mach twice during the flight (once during booster burn, then again during sustainer burn).

Mark used the miniAlt/WD altimeter and miniTimer timers in all of his projects.
